Connector check: C-301 ETACS-ECU Q: Is the check result normal? YES : Go to Step 2. NO : Repair the defective connector. STEP 2. Resistance measurement at the C-201 wiring harness side. (2) Measure the resistance between the C-201 column switch connector terminal No. 4 and the OK: Continuity exists (2 Ω or less) Q: Is the check result normal? YES : Go to Step 4. NO : Go to Step 3. STEP 3. Wiring harness check from C-201 Q: Is the check result normal? YES : The trouble can be an intermittent malfunction (Refer to GROUP 00 − How to use Troubleshooting/inspection Service − How to Cope with Intermittent Malfunction ). NO : Repair the wiring harness. STEP 4. Voltage measurement at the C-201 wiring harness side. (2) Measure the voltage between the C-201 column switch connector terminal No. 1 and the body OK: System voltage Q: Is the check result normal? YES : Go to Step 6. NO : Go to Step 5. STEP 5. Wiring harness check between the C-201 Q: Is the check result normal? YES : The trouble can be an intermittent malfunction (Refer to GROUP 00 − How to use Troubleshooting/inspection Service − How to Cope with Intermittent Malfunction ). NO : Repair the wiring harness. STEP 6. Check the wiring harness wires between Q: Is the check result normal? YES : Go to Step 7. NO : Repair the wiring harness. STEP 7. Check whether the diagnosis code is |
